In quadrilaterals, which of them have their diagonals bisecting each other?

Answer: 48 cm.

Step-by-step explanation: Area of a triangle is equal to (base * height) / 2. (12 * 8) / 2 = 48

Answer:

The answer is 60

Step-by-step explanation:

m∠CAB = 180° − 90° − 30° = 60°

Answer:

55.5 cm^2

Step-by-step explanation:

9x 9 x 1/1= 40.5

3x5= 15

40.5+15=55.5

Answer:

A: Not proportional

B: Proportional

Step-by-step explanation:

A: 14/4 = 3.5

40/12 = 0.3333333333333

Therefore A is not proportional

B: 3/9 = 0.3333333333333

15/45 = 0.3333333333333

Therefore B is proportional

Gotcha, bro.

(I don't know what pi is, so I'm gonna assume that it is 3.14)

C=pi x diameter

First, multiply the radius by 2 so you have the diameter.

3x2=6

Second, multiply 3.14 (pi) by 6 (diameter)

3.14x6=18.84

Therefore, the circumference is 18.84.

(19 if you round it to the whole number)

Hope this helps!

(btw if pi is something else, use these steps to help you out)

The circumference of the circle is 6π meters.

A circle is a two dimensional figure with a radius and circumference of 2πr.

We have,

The circumference of a circle is given by the formula:

C = 2πr

where r is the circle's radius and π (pi) is a mathematical constant approximately equal to 3.14.

In this case, the radius of the circle is 3 meters.

Substituting this value in the formula, we get:

C = 2πr

C = 2π(3)

C = 6π

Therefore,

The circumference of the circle is 6π meters.

Answer:

x > 1

Step-by-step explanation:

Subtract 3 from both sides

8x + 3 - 3 > x + 10 - 3

Simplify

8x > x + 7

Subtract x from both sides

8x - x > x + 7 - x

Simplify

7x - 7

Divide both sides by 7

7x/7 > 7/7

Simplify

x > 1

Answer:

10

Step-by-step explanation:

You make a proportion 9/6=15/x then multiply 6 and 15 and divide it by 9

The height the 15 ft building touches the building is approximately 10 ft.

The ladder is 9 ft tall and leaning on a wall that is 6 ft above the ground.

The situation forms a right angle triangle.

Therefore, let's find the angle made by the 9 ft ladder and then use it to find the height the 15 ft ladder touch the building.

Using trigonometric ratios,

let

∅ = angle

tan ∅ = opposite / adjacent

tan ∅ = 6 / 9 = 2 / 3

∅ = tan⁻¹ 0.6666666

∅ = 33.6900672615

Therefore, the height the 15 ft ladder touch building can be calculated as follows:

tan 33.69 = h / 15

h = 15 × 0.66666496431

h = 9.99997446476

h ≈ 10 ft.

Answer:

A

Step-by-step explanation:

A good trick for trigonometric functions is to remember SOHCAHTOA:

Sin=Opposite over Hypotenuse

Cos=Adjacent over Hypotenuse

Tan=Opposite over Adjacent

The red arrows on the attachment indicate where opposite, hypotenuse, and adjacent are for angle A.

So in this case, the sin of angle A (opposite over hypotenuse) would be [tex]\frac{24}{26}[/tex] and cos A (adjacent over hypotenuse) would be [tex]\frac{10}{26}[/tex].

The point (-3,1) is not passing through the graph y = -2x + 7 so option (C) will be correct.

A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.

In order to plot the graph, we need to find out y's values corresponding to x's value

After that, we need to substitute the values of x's and y's into the coordinate geometry.

Given that a line  y=-2x+7

Now in order to satisfy any point of this function then the value or

coordinate should satisfy the function or line.

So by checking option (A) 9 = -2(-1) + 7 = 9 so its satisfy.

So all options except (C) are satisfying.

Option (C) ⇒

-2(-3) + 7  ≠ 1

Hence "The point (-3,1) is not passing through the graph y = -2x + 7".
